Аннотация: Many proteins require a non-covalently bound ligand to be functional. How ligand binding affects protein conformation is often unknown. Here we address thermal unfolding of the free and ligand-bound forms of photoprotein obelin. Fluorescence and far-UV circular dichroism ( CD) data show that the various ligand-dependent conformational states of obelin differ significantly in stability against thermal unfolding. Binding of coelenterazine and calcium considerably stabilizes obelin. In solution, all obelin structures are similar, except for apo-obelin without calcium. This latter protein is an ensemble of conformational states, the populations of which alter upon increasing temperature. (C) 2012 Federation of European Biochemical Societies.
